 * A data access object (DAO) providing persistence and search support for Halls
 * entities. Transaction control of the save(), update() and delete() operations
 * can directly support Spring container-managed transactions or they can be
 * augmented to handle user-managed Spring transactions. Each of these methods
 * provides additional information for how to configure it for the desired type
 * of transaction control.
